Why Do We Need a New FuelSource?
Currently our machinery runs on oil
Oil pollutes and there are limited supplies
Hydrogen is the most abundant elementin the known universe
Hydrogen fuel cells do not pollute

How A Hydrogen Fuel Cell Works
The fuel cell is composed of ananode, an electrolytemembrane in the center, and acathode.
Hydrogen flows into the fuelcell anode. Platinum coatingon the anode helps to separatethe gas into hydrogen ions andelectrons. The electrolytemembrane allows only theprotons to pass through themembrane to the cathode sideof the fuel cell. The electronscannot pass through this
membrane and flow through anexternal circuit in the form ofelectric current.

Where Will Hydrogen ComeFrom?
Hydrogen is not readily available forconsumer use yet.
To get around this problem, hydrogen willbe extracted from other, moreconventional types of fuels by a devicecalled a reformer.
A fuel like natural gas is reformed intohydrogen which will then go on to powera fuel cell.

Where Will Hydrogen ComeFrom?
Natural gas comes from mostly the US,so even before the switch to purehydrogen is made, we will get our fuel
domestically.
Natural gas production could peak by2025

Hydrogen Powered Cars
Hydrogen cars run clean. 500 cubic tons of carbon removed from
atmosphere by 2040
New design possibilitiesbecause of compacthydrogen fuel cell
stack. Stack of 200 cells
is the size of a
home PC.

Hydrogen Powered Cars
Quieter operation than normal carsbecause of no moving parts in the fuelcell stack and electric motors at the
wheels.
Possibility of interchangeable bodies.

Hydrogen in the Home and
Office Hydrogen fuel cells will power and heat
homes and offices.
Hopefully this will start in about 10 years. The hydrogen will come from natural gas
that has gone through a reformer. Hydrogen cars can be refueled in the
garage by a hydrogen powered house.

Much of the worldsand Americas oil
comes from the
Middle East. This is an
incredibly volatile
region. Oil runs the
economy in thesecountries

Hydrogen fuel cells mean a decreasedneed for Middle Eastern oil.
Decreased imports by the US means adecreased military presence in theMiddle East.
Possible economic collapse in main oilexporting nations and in places like SaudiArabia, this could lead to revolution.
Possible no-win situation for the US.

Conclusion
Hydrogen fuel cells will dramaticallychange our cars, how are homes andbusinesses are powered and heated, and
it both positively and negatively changeplaces like the Middle East and thirdworld countries. They will also clean up
the worlds air.
